UNITED STATES PATENT OFFICE.

CHARLES ELIS BRATT, OF STOCKHOLM, SWEDEN.

CYLINDRICAL CASK.

SPECIFICATION forming part of Letters Patent No. 503,575, dated August22, 1893. Application filed June 11, 1892. Serial No. 436,411. (Nomodal.) Patented in Sweden July 28. 1891, No. 3,507.

To all whom it may concern:

Be it known that I, CHARLES ELIs BRATT, a subject of the King of Swedenand Norway, and a resident of Stockholm,in the Kingdom of Sweden, haveinvented a certain new and usefullmprovement in Cylindrical Casks, (forwhich I have obtained a patent in Sweden, No. 3,507, bearing date ofJuly 28, 1891,) of which the following is a specification.

It is the object of my invention to provide a cylindrical cask or barrelthe parts of which may be readily put together or knocked down forpacking or for return transportation.

It is my object to provide a cask which will be strong and simple and inwhich the greater part of the staves may be of any ordinary form.

In the drawings, Figure 1, is a side view of the cask as set up, andFig. 2, is a plan View.

In the drawings the hoops are shown at 1, within which are placed thestaves 2. These staves are of the same width throughout and they may bealike in all respects and of practically ordinary form.

In order to complete the cask and at the same time lock all the staves 2(which have preferably tongue and grooved edges 3, Fig. 2)

together I use two wedge shaped staves 4, 4 the inclined edges 5, ofwhich are in contact as in Fig. 1 while the straight edges bear on theadjacent straight edges of the ordinary staves 2. The tapered ends ofthe staves are turned in opposite directions. By forcing these wedgeshaped staves into proper position the wedging action will jam all theother staves about the cask together so that their edges will interlockand thus form a complete tight and strong cask.

While I have shown a cylindrical cask I do not wish to limit myselfstrictly to this form.

I claim- A cask consisting of a series of staves having parallel edgesand two wedge shaped staves for looking all the staves in place andforcing them tightly together, the tapered ends of said staves beingturned in opposite directions and driven in between the other staves,substantially as described.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.

CHARLES ELIS BRATT.
